Two years of data exist in A/P Transfer file

[QSILVER]

I have a strange problem with my A/P transfer file. When I printed it out prior to moving it over to the GL module, I noticed it contains both 2009 & 2010 entries???
I have already processed A/P invoices and payments since closing 2010 so I can't use a backup to Restore the files. Besides manually deleting the entries once they get brought into the GL, is there any way to fix this?
I suspect it may have to do with the A/P year end closing process and the Historical Detail option. Any idea as to how I created this mess?

You failed to transfer the AP Temporary General Ledger Transfer file from last year, so the 2010 AP entries for the same period were appended to the prior file. This file is deleted by the GL following the Transfer (Import).

OK, that makes sense. From now on I'll look for transfer files being left on the system and rename them to avoid this in the future. Thanks!
